My Dad at almost 93 still runs up and down between Cape Cod and the Boston area as he closes out a home there. We finally got him and my 92 year old Mother into a lovely tiered community in a lifecare unit with services for her. Well, they both are impossible and are going to give the place a year ... why because there are so many old folks. She has short-term memory, and he does not realize why nobody will ride with him any where. You would think he would be thankful to be in an area where he could still drive short distances for a while in daytime and then have their transportation services at his use. It is very hard to deal with the elderly, and I just hope we will not be like them. But in any case, you do need to take the upper hand in this case. You may want to do some research to see if there is para-senior bus transit in his area or the price of cabs for seniors. Also check to see if there is any group with volunteers who might provide free rides for medical appointments for seniors and any shopping services which would bring his food order to him. If he knows he won't be "stranded," and have access to services it may help.
